TIR E'FOR CYCLES OR OTHER WHEELS.

SPECIFICATION forming part of Letters Patent N 0. 637369, dated November 21', 1899. Application filed February 1, 1899. Serial No. 704,080. (No model.)

To all whom it may concern: Be it known that I, OSCAR LAVANGHY, merchant, of Vevey, Switzerland, have invented certain' new and useful Improvements in Tires for Cycles or other Wheels, of which the-following is a specification.

This invention relates to improvements in tires for cycles or other wheels intendedto replace the well known pneumatic ti res,which are very rapidly worn out. p

The chief object of my invention is to replace the combined air-tube and jacket inclosing the same of the pneumatic tires at present constructed by a flexible metallic tire presenting approximately the same advantages as those pneumatic tireswith respect to their elasticity and being much more durable, being not exposed to wear and abrasion and moisture and other deleterious influences to which the pneumatic tires are exposed.

In my improvement the flexible metallic tire is fluted in cross-section and'thus formed with circumferential ribs.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 a cross-section,

representing my invention; and Figs. 3 and 4 are cross-sections of two modifications of the flexible metallic tire. I

In all the figures the sameletters of reference refer to the same parts;

In the construction Figs. 1 and 2 the wheelrim B is provided with suitably-folded edges b and 6 forming two circular grooves, in which are engaged the edges of a flexible fluted steel band A, madeof several sections A A A 850., which are arranged to overlap one another, as shown in Fig. 1. D are the spokes which connect the wheel-rim B to the hub, which may be of any of the Well-known constructions, and dj are springs or equivalent holding devices fixed across the rim B at suitabledistances fromone another, the'object of which is to hold the rim to'shape and prevent the rim spreading when the flexible steel bands are depressed and also to prevent the tendency of dislodgingthe edges bjand b of the rim B from one another.

In themodification Fig. 3 theflexible mtallic tire is formed of a fluted circle A, of

of one piece all around the Wheel. The steel wheel-rim is here formed of two'flan'ged'portions B and B which are connected with one another at the flanges by means of suitable steel, of the fluted section shown and made .7

screws or bolts E, placed at suitable in'tervals -and fixed to the spokes D, which-are suitably forked, as show I In the modification in Fig. ithe tire A of fluted cross-section is formed as a' tubular ring of sheet metal, theiriner edges of which are brought together and connectedto the forked spokes D by means of the two portions B and B of therim by the screws or bolts E. Having thus fully described myinvention, I claim In a wheel, the combination with the spokes, of a rim having inwardly-turned-over edges and a flexibletire formed of spring sheet metal fluted in cross-section and having edges adapted to be received and held by the turned-over edges of the rim, and having transverse springs extending across the rim, substantially asset forth."

In testimony that I claim the foregoing as my invention I have signed mynamein presence of two subscribing witnesses.
